Neither Cedric Watson nor Dirk Powell were born or raised in French Louisiana, but both men felt its pull so strongly they had to pack up and move to Acadiana. Fiddler/accordionist Watson heard French language and music on the radio in Texas, soaked up as much as he could until he was able to make the pilgrimage to his ancestral territory and explore his roots, forming the Grammy-nominated Bijou Creole (who will be returning to Philly April 12 for Allons Danser). Fiddler Powell is an Appalachia-rooted multi-instrumentalist who grew up in Ohio with classical training but learned traditional, from his grandpa back in Kentucky. Once your ears are open to tradition, it rarely stops with one strain. Powell met and wooed Christine Balfa — daughter of legendary Cajun fiddler Dewey Balfa — and studied under her father. Watson (pictured) and Powell have become revered musical ambassadors for their adopted home, but not usually as a duo — so this Saturday’s Crossroads team-up is a special treat.
